Sickle weapon location?

[Fehute]

I've found all of the weapons in the armory except for the sickle (next to the throwing weapons). Any hints to where it is? Or at least some encouragement that it does exist?

I'm pretty sure I've found one in a box/barrel in the Crypt level. There are also some set-pieces, like the forge room in the crypt, that have a bunch of rare weapons in them.
